On the basis of real-time observation of their fusing action, the mechanism of losing its transparency is discussed.  The observed loss drop is found to be an overlap of decoupling of the circuit and transient light flux from the burned coating.  The critical input power to blow out is expected to be raised by eliminating its insertion loss.

This structure was made by splicing single-mode silica fibers through TeO2 glass melt to form a necked bridge, which was coated with carbon-containing paint after quenching it.  Optical fusing action was induced by 0.3--1.5 W of CW light (1.54 um) and its output power dropped by 12 dB on average.  Optical decoupling seems to be induced by  not only deformation but also crystallization of the glass bridge.  Its quite a high insertion loss of about 2dB can be reduced by introducing some refractive index modulations into the present structure.

This phenomenon is useful to make irreversible optical limiting devices known as optical fuse.  The present structure breaks by 1.2-5.3 W of incident light (~1.5 um), exhibits low insertion loss of less than 1 dB, and is formed by dipping-up a small amount of hot glass melt between fibers, aligning the fibers and quenching them.  The relation between shape of the captured melt and its insertion loss is discussed.

summarized.  From a macroscopic viewpoint, the dissipative soliton
concept and an analogy with grassfire help us understand this strange
phenomenon.  The strong heat-induced absorption of silica glass and the
highly confined supply of laser energy cause captured plasma to shift to
the light source along the fiber leaving catastrophic damage behind it.
From a microscopic viewpoint, the periodic void formation process was
unveiled by the statistical analysis of void shapes and ultra-fast
videography.  The bullet-like shape of the damage train results from the
formation of an intrinsic bridge inside the hollow silica melt behind
the traveling plasma and the successive compression of detached voids
under a steep temperature gradient along the fiber."
